This list summarizes the most important breaking changes in Beats. For the complete list, go to Beats breaking changes.

Known issue with Kafka outputedit

The Kafka output fails to connect when using multiple TLS brokers. We advise not to upgrade to Beats 7.8.0 if you’re using the Kafka output in this configuration.

APM Instrumentationedit

Libbeat includes the Elastic APM Agent for instrumenting the publishing pipeline. Currently the Elasticsearch output is instrumented. APM can be enabled simply with setting the ELASTIC_APM_ACTIVE environment variable to true when starting the beat. To make tracing possible, the Publish method of the Client interface takes a Context object as first argument. That Context is intended for propagating request-scoped values, not for cancellation.
